> Hi, i was implementing my own Handler, which generated an (errrr) 
> NullPointerExcpetion in StartDocument() callback. This was my bug, BUT 
> AbstracSaxParser.parse() chatches my Exception and rethrows it. This makes it 
> look like line 'throw new SAXException(ex);' had a NullPointerException. MayBe 
> there is a good reason to catch any Exception here, but i don't understand it. 
> I would expect a 'exception tunneling', i.e. exceptions in the users callback 
> should be recognizable as such. Thanks for your time.
